' IMPROVEMENT IN RUNNING-GEARS FOR WAGONS.

Specification forming part of Letters Patent No. 214,633, dated April22, 1879; application filed January 30, 1879.

10 all whom it may concern:

Be it known that I, ROBERT W. DAVIS, of Elmira, in the county of Ohemungand State of New York, have invented certain'new and useful Improvementsin WVagon Gears, of which the following is a specification.

The object of my invention is to produce a running-gear for a wagon orcarriage which maybe made very strong and durable and having a verylight appearance.

My invention consists in a certain novel construction of the partscomposing the runninggear of a wagon, consisting in the use of both woodand metal, whereby the desired end is attained.

In the accompanying drawings, Figure 1 represents a plan view of awagon-gear of the kind usually employed in wagons for conveying heavyloads; Fig. 2, a transverse section thereof on the dotted line :0 m,Fig. 1; and Fig. 3, a transverse section on the dotted line y 3 Fig. l.

Similar letters of reference designate correspondin g parts in all thefigures.

A A designate the axles of a wagongear embodying my improvements, whichmay be of iron of the kind usually employed. These axles are eachsurmounted by a bolster, B, the one above the hind axle being securedrigidly thereto, while the forward bolster is pivoted by a king-bolt, a,to a pintle-plate, 1), upon which it may freely turn. I construct thesebolsters of iron, and may make them of the form represented in Figs. 2and 3, as thereby the requisite amount of strength may be securedwithout using a large amount of material. As there represented, the hindbolster is formed of plates 0, of metal, of different lengths, two ormore of which may be used.

The ends of each of these plates 0 are deflected or bent downward, so asto rest upon the top of the axle.

The longer plates are placed uppermost, and.

thin metal, 0 having its two ends bent over and' secured together, and acentral brace, 0 for giving it the requisite strength.

Near each end of the bolsters B are stakes C, as in ordinary Wagons.These stakes are composed of a metal shell and a wood filling. The metalshell is formed with a foot, having its sides and end prolonged belowthe upper plate of the bolster, the said foot resting upon the angularcorners c.

D D designate the hounds of the wagon. These are preferably straight, and are composed of a metal shell and wood filling. They are securedrigidly to the forward axle by means of rivets or bolts, and areprovided at or near their rear ends with lateral arc-shaped braces ff,which serve to prevent their displacement relatively to each other andwith braces g, which aid in securing them to the axle.

The brace f is shown as having its ends inserted between the sides ofthe metal shells of the hounds, abutting against the wood fill- Edesignates a plate of metal, having its ends deflected or bent andresting upon the forward axle, to which they are secured by means ofclips d. A shorter plate, h, is secured between the plate E and theaxle, and serves as a brace to bind the two firmly together. The plate Eforms a support for the pintle-plate b, and serves as a means forsecurely holding the hounds D D, which may pass between it and the axle.The ends of each hound D are connected by braces i, which are securelyheld by the clips cl.

The pole F is represented as provided, upon its rear end, with askeleton frame-work, j, of metal, and is secured between the hounds by abolt or rod, k. v

The forward and hind axles are shown as connected together by a reach,G, which is se-.

which are represented as also formed of a shell or covering of metalfilled with wood. I I designate metal braces, which extend from thereach, and are secured to the hind axle, near the ends thereof, by theclips 01.

By'my invention I produce a wagon-gear of great strength, and as thevarious parts are covered with metal, a fine smooth appearance is giventhem. The various parts of the wagongearmay bepainted and variouslyornamented, as is usual when said gear is made of wood.

With slight modifications some or all of my improvements may be appliedto Wagons and carriages of various kinds.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The front bolster composed of the single plate or bar 0 having itstwo ends bent under having the plate cbent at right angles to formvertical legs or supports, of the stakes O, having hollow feet restingupon and embracing the corners of said bolster, and provided withdownwardly-extending sides for bracing said stakes against lateralstrain, substantially as described.
